Question

write notes on nerve cell

Answer 1

Nerve cell-  Nerve cells are also known as neurons.

• Neurons or nerve cells are structural and functional units of the nervous system that carry impulses from one place to other.

• Neuron is the largest cell of the body which measures to about few metres in length.
• Neuron has the ability to generate and conduct electrochemical impulses.
• Every neuron has three main parts, viz. cyton or cell body, axon and dendrites. Dendrites pick up the electrochemical signals produced.
• These signals are transferred to cyton and from cyton they are sent to axons. From axon of one neuron, the impulse is then given to dendrites of next neuron.
• The cells called neuroglia support the nerve cells and help in their functioning. Nerve is formed of neurons and neuroglial cells together
